I have a dc sports 4-2-1 header and thermal 2.25 inch exhaust. I want the carsound cat with 2.25 inlet and outlet right? and does anyone know the part #? Also, what kind of gains should I suspect?

 

small gains, are you looking for the part # for the carsound?

 

yea... do you know the #?

 

IM Dave (screen name is SMSP). He sells them and can provide any info you need.

SMSP = great resource

 

You can't just say "small gains"

The gains are going to be dependant on his total engine package, and how much of a bottle neck the stock cams are.

Running high compression and wild cams with a stock cat? opening up the cat to flow correctly with the rest of an exhaust system is going to unbottle some impressive gains.

 

Carsound Part #94005 or 94105
